Systems and methods for generating an instrument positioning map for positioning one or more instruments on a patient body

ABSTRACT

Various methods and systems for generating an instrument positioning map for positioning one or more instruments on a patient body. The methods further correspond to tracking an image of the patient&#39;s body together with a known visual landmark positioned at a defined position on the patient&#39;s body and receiving image data, wherein the image data comprises a real-time image of the patient&#39;s body and the known visual landmark. The methods further include receiving user input identifying a mapping location of one or more instruments relative to the known visual landmark on the real-time image of the patient&#39;s body and generating an instrument positioning map for the patient by overlaying the mapping locations of the one or more instruments onto the image data, wherein the instrument positioning map comprises data locating the mapping location of each of the one or more instruments relative to the known visual landmark.

BACKGROUND

An electrocardiogram (ECG) is commonly used in the assessment of cardiovascular disease. For example, these tools (e.g., Ambulatory ECG monitoring devices such as the Holter monitor) are configured to record electrocardiograms of a patient via a plurality of specially-placed electrodes that must be attached to the patient's torso. From these electrodes, electrical signals from the patient's body are measured and/or derived to record the average electrical activity generated and/or to monitor cardiovascular characteristics of the patient. However, these tools are carefully calibrated to the detection of signals from electrodes that must be carefully placed on defined areas of the patient's torso to properly record signals of the patient's body. These electrodes need to be positioned on the patient's torso precisely to obtain accurate signals. In certain instances, poor electrode placement can result in inaccurate signal generation, which can ultimately lead to incorrect diagnosis of the patient's healthcare issues, ineffective treatment prescriptions, and potentially increased rates of hospitalization for the patient.

When prepping a patient for ECG testing using the ECG monitor device, clinicians must remember where each electrode needs to be attached on the patient. Even a slight deviation in electrode placement of a few millimeters away from the correct position can have significant effects on the accuracy of generated signals. The placement of electrodes requires experience and training to find anatomical landmarks on patients of different shapes and sizes. Even a skilled clinician trained in using both visual and palpatory cues to identify the anatomical landmarks may still need to devote a significant amount of time for the proper placement of the electrodes. In a typical hospital setting or in an emergency, a clinician may not have the extra time to properly palpate the patient. An inexperienced clinician, a layman, or the patient may find such ECG monitor device attachment too complex. As a consequence, electrodes and ECG leads are often misplaced. Accordingly, there is a need for systems and methods for facilitating the placement of electrodes of ECG monitoring devices on patients.

DETAILED DESCRIPTION

Various embodiments of the present invention now will be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all embodiments of the inventions are shown. Indeed, these inventions may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. The term “or” is used herein in both the alternative and conjunctive sense, unless otherwise indicated. The terms “illustrative” and “exemplary” are used to be examples with no indication of quality level. Like numbers refer to like elements throughout.

I. OVERVIEW

Various embodiments encompass an Augmented Reality (AR) system to facilitate placement of electrodes onto a patient's body (e.g., electrodes of an ECG monitoring device). Specifically, certain embodiments are configured for generating AR-based instrument positioning maps comprising visual instrument positioning identifiers corresponding to appropriate electrode placements on a patient's body. These AR-based instrument positioning maps may be generated specifically for a particular patient, for example, through clinician-guided mapping processes, and a resulting instrument positioning map may be stored in a manner accessible to the patient via an AR-enabled device. For example, certain embodiments enable the generation of complex (e.g., 12-lead/electrode) ECG placement maps where the instrument positioning map is generated and shown to a user using graphical mapping locations in an AR view. The instrument positioning map may be used to guide a user to align an electrode with a predetermined instrument location.

Various embodiments of the invention utilize real-time image tracking of a patient's body (specifically, a patient's torso) within an AR-view environment to facilitate placement of electrodes and ECG leads by a clinician during a mapping process. Additionally, a system is provided for recording the placement of the electrodes and ECG leads via the AR-view during the mapping process, so that patients can later retrieve the generated instrument positioning map and utilize the instrument positioning map within a patient-oriented AR view to self-place the electrodes and ECG leads using the same guidance as provided by the clinician and reflected within the instrument positioning map. The guidance is provided via an AR overlay reflective of the generated instrument positioning map over the digital image of the patient's body, utilizing a known visual landmark for positioning of the instrument positioning map. The instrument positioning map of certain embodiments thus indicates where specific electrodes should be placed on the patient's body. Moreover, the AR overlay may be customized by a medical professional, for example by moving overlaid recommended electrode and ECG lead positions to better fit with the patient's body type.

A. Technical Problem

The current process for electrode and ECG lead placement is a largely error-prone, complicated, and time-consuming human-based task subject to significant potential human errors. Often, patients are given written (or visual) instructions for placement of electrodes and ECG leads, with references to anatomical landmarks (visual or otherwise) that may or may not be pronounced based on the patient's own musculoskeletal makeup. This process typically involves some guess-work on the part of the patient to translate specific locations from a skeletal system diagram to a patient's own skeleton covered by skin, muscle and adipose tissue. In a large number of cases, false ECG diagnosis resulting from improper lead placement has the potential to trigger the wasteful use of healthcare resources and even cause harm to patients.

Existing solutions to address some of these challenges such as referencing instruction manuals and diagrams provided by ECG monitoring device manufacturers, watching videos, and training with experts provide some assistance to patients, however, these solutions still do not accommodate and/or address specific musculoskeletal features of the specific patient, to minimize the likelihood of human error in placement of specific electrodes and ECG leads on a patient.

B. Technical Solution

To solve the foregoing technical problems, an exemplary embodiment of the present invention provides an AR system by utilizing AR to provide an AR visual environment and guidance of the electrodes and ECG leads' positions within the body of the patient. The AR visual environment comprises AR-based instrument positioning maps comprising visual instrument positioning identifiers corresponding to appropriate electrode placements on a patient's body. Various embodiments utilize a real-time digital image of a patient's body and a known visual landmark (e.g., image target) determined to be linked to AR content (e.g., AR-based instrument positioning maps comprising visual instrument positioning identifiers corresponding to appropriate electrode placements on a particular patient's body).

The AR system provides the AR visual environment in real time by identifying and registering a known visual landmark that is centered and vertically aligned to a patient's chest. The visual landmark is identified and compared against a reference image (e.g., known visual landmark or reference image target) of an image target database or a cloud-based image target database used for identification. If there is a match, the AR system retrieves AR content linked with the identified visual landmark and renders the AR content on a display screen of an AR device such as a head-mounted display (HMD), computer monitor, mobile device, high definition TV, and the like. After the visual landmark is identified, users (e.g., patients and clinicians) may activate a camera or the AR device to perform real-time tracking of the visual landmark positioned at a defined position on the patient's body to interact with the AR content linked to the visual landmark.

In another example embodiment, the AR system provides the AR visual environment in real time using the reference image without having to upload the reference image to the image target database or the cloud-based image target database. The reference image is stored locally on the clinician client device and/or patient client device and when the reference image is recognized in the real-world via the visual landmark, the AR system is configured to render the AR content for display.

Furthermore, this AR system coupled with the generated AR-based instrument positioning maps may serve as a training tool for clinicians and patients. The AR system includes AR training content (e.g., video of clinician-guided AR mapping processes). The present disclosure does note that according to Health Insurance Portability and Accountability Act (HIPAA) guidelines, the patient's face is never captured in accordance with certain embodiments. Any patient data and real-time images received by the AR system are temporarily displayed on the clinician client device and/or patient client device to show how the AR-based instrument positioning maps are overlaid over and positioned relative to the image of the user's body in accordance with any health organizational policies, HIPAA, or any other privacy or security laws. The AR video is provided to assist the patient in placing electrodes. This is especially beneficial for inexperienced clinicians, students, and patients in developing intuition and proper decision-making abilities with regards to the placement of electrodes. At least one advantage of generating an AR visual environment is the ability to accurately align real-time visual trackers (e.g., visual instrument positioning identifiers) on a patient's body, which are used to determine an exact position of electrodes, resulting in satisfactory feedback when positioning the electrodes with a predetermined instrument location. Accordingly, the AR visual environment can offer a rich source of information, improved documentation, and communication which will have implications for quality of service and patient health. Moreover, the AR visual environment provides step-by-step instructions to guide clinicians through selecting electrode placement according to clinician and/or ECG monitoring device manufacturer guidelines.

FIG. 2 provides a schematic of circuitry 200, some or all of which may be included in, for example, Augmented Reality Instrument Positioning (ARIP) system 130 and/or user computing entities 110A-110N. Any of the aforementioned systems or devices may include the circuitry 200 and may be configured to, either independently or jointly with other devices in a network 120 perform the functions of the circuitry 200 described herein. In general, the terms computing entity, entity, device, system, and/or similar words used herein interchangeably may refer to, for example, one or more computers, computing entities, desktop computers, mobile phones, tablets, phablets, notebooks, laptops, distributed systems, items/devices, terminals, servers or server networks, blades, gateways, switches, processing devices, processing entities, set-top boxes, relays, routers, network access points, base stations, the like, and/or any combination of devices or entities adapted to perform the functions, operations, and/or processes described herein.

In one embodiment, these functions, operations, and/or processes can be performed on data, content, information, and/or similar terms used herein interchangeably.

As illustrated in FIG. 2, in accordance with some example embodiments, circuitry 200 can includes various means, such as processing element 205, volatile memory 207, non-volatile memory 206, communications interface 208, instrument positioning repository 150, ARIP application 130, and/or input/output circuitry 216. As referred to herein, “circuitry” includes hardware, software and/or firmware configured to perform one or more particular functions. In this regard, the means of circuitry 200 as described herein may be embodied as, for example, circuitry, hardware elements (e.g., a suitably programmed processor, combinational logic circuit, and/or the like), a computer program product comprising computer-readable program instructions stored on a non-transitory computer-readable medium (e.g., non-volatile memory 206) that is executable by a suitably configured processing device (e.g., processing element 205), or some combination thereof.

Input/output circuitry 216 may be in communication with processing element 205 to receive an indication of a user input and/or to provide an audible, visual, mechanical, or other output to a user (e.g., provider and/or consumer). As such, input/output circuitry 216 may include support, for example, for a keyboard, a mouse, a joystick, a display, a touch screen display, a microphone, a speaker, a RFID reader, barcode reader, biometric scanner, and/or other input/output mechanisms. In embodiments wherein circuitry 200 is embodied as a server or database, aspects of input/output circuitry 216 may be reduced as compared to embodiments where circuitry 200 is implemented as an end-user machine (e.g., consumer device and/or provider device) or other type of device designed for complex user interactions. In some embodiments (like other components discussed herein), input/output circuitry 216 may even be eliminated from circuitry 200. Alternatively, such as in embodiments wherein circuitry 200 is embodied as a server or database, at least some aspects of input/output circuitry 216 may be embodied on an apparatus used by a user that is in communication with circuitry 200. Input/output circuitry 216 may be in communication with the volatile memory 207, non-volatile memory 206, communications interface 208, and/or any other component(s), such as via a bus. One or more than one input/output circuitry and/or other component can be included in circuitry 200.

Instrument positioning repository 150 and ARIP system 130 may also or instead be included and configured to perform the functionality discussed herein. In some embodiments, some or all of the functionality may be performed by processing element 205. In this regard, the example processes and algorithms discussed herein can be performed by at least one processing element 205, instrument positioning repository 150, and/or ARIP system 130. For example, non-transitory computer readable media can be configured to store firmware, one or more application programs, and/or other software, which include instructions and other computer-readable program code portions that can be executed to control each processor (e.g., processing element 205, instrument positioning repository 150, and/or ARIP system 130) of the components of circuitry 200 to implement various operations, including the examples shown above. As such, a series of computer-readable program code portions are embodied in one or more computer program goods and can be used, with a computing entity, server, and/or other programmable apparatus, to produce machine-implemented processes.

As indicated, in one embodiment, circuitry 200 may also include one or more network and/or communications interfaces 208 for communicating with various computing entities, such as by communicating data, content, information, and/or similar terms used herein interchangeably that can be transmitted, received, operated on, processed, displayed, stored, and/or the like. For instance, the circuitry 200 may communicate with other computing entities, one or more user computing entities 110A-110N, and/or the like.

As shown in FIG. 2, in one embodiment, the circuitry 200 may include or be in communication with one or more processing elements 205 (also referred to as processors, processing circuitry, and/or similar terms used herein interchangeably) that communicate with other elements within the circuitry 200 via a bus, for example, or network connection. As will be understood, the processing element 205 may be embodied in a number of different ways. For example, the processing element 205 may be embodied as one or more complex programmable logic devices (CPLDs), microprocessors, multi-core processors, coprocessing entities, application-specific instruction-set processors (ASIPs), and/or controllers. Further, the processing element 205 may be embodied as one or more other processing devices or circuitry.

User computing entity 110A may include an image tracking device such as image tracking device 170 comprising a plurality of sensors to obtain information regarding the user's body and the environment of the user computing entity 110A. Alternatively or in addition, user computing entity 110A the device can include a set of REST-based APIs so that the device can communicate with the image tracking device. The plurality of sensors of the image tracking device may include image-based sensors, such as imaging cameras or optional sensors to obtain visual information (imagery). These sensors also may include non-image-based sensors, such as Global Positioning System (GPS) receivers, accelerometers, gyroscopes, solid state compasses, radio-frequency identification (RFID), wireless interfaces (e.g., IEEE 802.11 transceivers or Bluetooth™ receivers), magnometers, ambient light sensors, and the like. In some embodiments, the ARIP system uses information from the plurality of sensors to determine one or both of a position and orientation of the image tracking device relative to the tracked imagery from the real-world environment. For example, as the user moves and interacts with real-world objects (e.g., electrodes) in the AR-view environment provided by the ARIP system 130, the image tracking device may detect changes in the position/orientation of the image tracking device (and the user's body) and render for display new AR content (e.g., the generated instrument positioning map) to overlay over the image of the user's body. Additionally, the image tracking device may detect changes in the scale, zoom, or size of the AR-view and adjust accordingly.

In some embodiments, the image tracking device 170 is configured to utilize a visual-inertial odometry technique which combines information from the plurality of motion sensors with computer vision analysis of the real-world environment visible to the tracking device 170 camera. AR processing is then performed by processing element 308 to recognize and track positions of real-world objects or features from the real-world environment.

The AR content overlaid on the digital image of the user's body is generated using AR processing by processing element 308. The AR processing performed by processing element 308 may include object identification algorithms or other AR processing techniques used to create or identify AR information or real-world objects in the digital image or video sequence. In embodiments, the ARIP system 130 may utilize the image tracking device and AR processing algorithms to identify a known visual landmark in the digital image or video sequence scene. As discussed herein, the known visual landmark may be embodied as a specially designed AR image target (e.g. comprising one or more 2D bar codes having a known orientation relative to the patient's torso) linked to an AR-based instrument positioning map. In an example embodiment, the AR image target is utilized by processing element 308 as a reference image. The reference image may be stored locally on user computing entity 110A and once detected in the real-world environment, processing element 308 triggers AR content associated with the known visual landmark to be rendered. Detecting the known visual landmark positioned at a defined position on the user's body, the ARIP system 130 may then infer the 6-dimensional space of poses (e.g., X/Y/Z positions and roll/pitch/yaw orientations) of the image tracking device with respect to the known visual marker. Thereafter, the ARIP system 130 may render the AR-based instrument positioning map and graphics or positioning identifiers that overlay the digital image of the world in such a way that the AR-based instrument positioning map and positioning identifiers would be positioned or point to specific physical locations of the user's body (e.g., right clavicle at the midclavicular line). In some embodiments, the ARIP system 130 may transmit for rendering the AR content to an AR display (e.g., smart glasses, contact lenses, a heads-up display, a digital helmet, AR headset, and the like) of the display device 180 and/or user computing entity 110A.

C. Exemplary Holter Monitor and Electrode Placement

The ARIP system 130 includes one or more patient devices located with a patient and can be any device that gathers data from the patient such as, but not limited to, ECG, Electromyography (EMG), electroencephalogram (EEG), or Holter monitors. An example Holter monitor 400 is illustrated in FIG. 4. A Holter monitor is a small non-invasive ambulatory, portable ECG machine used to record the heart's electrical activity. This device has electrodes and electrical leads. The number and intended torso positioning of electrodes varies by model, but a 12-lead Holter monitor provides a complete picture of the heart's electrical activity by recording information through 12 different perspectives. A 12-lead Holter monitor may be preferred by some care providers for its precise ECG signal information required to analyze and detect arrhythmias and myocardial ischemia. To measure the heart's electrical activity accurately, proper electrode placement on the chest 401 is crucial. In a 12-lead ECG such as Holter monitor 400, there are 12 leads calculated using 10 electrodes. The 10 electrodes illustrated in FIG. 4 (and their corresponding intended placement) include: V1 (408)—Fourth intercostal space on the right sternum located between the right midclavicular line (402) and the midline (403); V2 (409)—Fourth intercostal space at the left sternum located between the midline (403) and the left midclavicular line (404); V3 (410)—Midway between placement of V2 (409) and V4 (411); V4 (411)—Fifth intercostal space at the left midclavicular line (404); V5 (412)—Anterior axillary line on the same horizontal level as V4 (411); V6 (413)—Midaxillary line (405) on the same horizontal level as V4 (411) and V5 (412); RA—Right Arm (406)—Anywhere between the right shoulder and right elbow; RL—Right Leg (415)—Anywhere below the right torso and above the right ankle; LA—Left Arm (407)—Anywhere between the left shoulder and the left elbow; and LL—Left Leg (416)—Anywhere below the left torso and above the left ankle. It should be understood that the illustrated positioning and electrodes are merely examples, as other monitor types may utilize different numbers and/or positioning of electrodes.

IV. EXEMPLARY SYSTEM OPERATION

The operation of various embodiments of the present invention will now be described. As discussed herein, various embodiments are directed to systems and methods for selectively and securely sharing user data with a facility to accommodate specific needs of a user.

The ARIP system 130 may be configured to provide a mobile device application such as an ARIP application (app) that is adapted to be stored in memory on the user computing entity 110A and may operate functionality related to one or more of: ECG testing preparation and patient-at-home ECG testing.

A. Exemplary Features Provided by ECG Testing Preparation

The AR ECG testing preparation module can include, for example the following features: (1) provision of an AR-view environment to facilitate placement of electrodes and ECG leads by a clinician during a mapping process using a preliminary AR-based instrument positioning map; (2) calibration of the preliminary AR-based instrument positioning map based on appropriate electrode and ECG lead placements on a patient's body and estimated electrode and lead placements utilizing a known visual landmark; (3) customization and personalization of the AR-based instrument positioning map comprising visual instrument positioning identifiers corresponding to appropriate electrode and ECG lead placements with respect to a patient's body; (4) generation and storage of a recordable AR video including the AR-based instrument positioning map so that patients can later retrieve the instrument positioning map and utilize the instrument positioning map within a patient-oriented AR view to self-place the electrodes and ECG leads using the same guidance as provided by the clinician and reflected within the instrument positioning map.

In an example embodiment illustrated by FIG. 5, the projection of the AR-view is generated by using display device 180, image tracking device 170, the AR image target (ARIT) 503, user computing entity 110A, 12-lead Holter monitor 400, or other specialized equipment. As illustrated in FIG. 5, ARIP system 130 is configured to superimpose an AR-based instrument positioning map 505 on a real-world imagery (e.g., imagery of the patient's 501 body) processed by the image tracking device 170 and display the combination of these on the display device 180 and/or the user computing entity 110A. The exact alignment of the patient's 501 body and the AR-based instrument positioning map 505 is important. As such, the ARIP system 130 is configured to accurately align both the patient's 501 body and the AR-based instrument positioning map 505 using an ARIT 503 placed at a defined position on the patient's torso, such as on the patient's jugular notch 1101 as shown in FIG. 11. The AR-view facilitates the optimal placement of electrodes of the 12-lead Holter monitor 400. This technique can be used to increase precision by providing AR-based instrument positioning maps comprising visual instrument positioning identifiers corresponding to appropriate electrode placements on a patient's body for a clinician 502 to consider and reference during the mapping process.

B. Exemplary Features Provided by Patient-Oriented-At-Home Testing

The AR ECG patient-oriented-at-home testing module can include, for example, the following features: (1) provision of an AR-view environment to facilitate placement of electrodes and ECG leads using AR-based instrument positioning maps comprising visual instrument positioning identifiers corresponding to appropriate electrode placements on the patient's body; (2) provision of feedback to the patient during placement of electrodes and ECG leads. In some embodiments the feedback is provided in real-time during the placement of electrodes and ECG leads, for example, as visual-based feedback queues, audio-based feedback queues, tactile (e.g., vibration)-based feedback queues, and/or the like, such that the feedback is useful to the patient and can provide additional guidance with regards to appropriate electrode and ECG lead placements on the patient's body.

In an example embodiment illustrated by FIG. 6, patient 501 is at home and can retrieve using user computing entity 110A and ARIT 503, the generated instrument positioning map and utilize the instrument positioning map within a patient-oriented AR view to self-place the electrodes and ECG leads using the same guidance as provided by the clinician and reflected within the instrument positioning map. The patient-oriented AR-view is generated by using display device 180, image tracking device 170, the AR image target (ARIT) 503, user computing entity 110A, 12-lead Holter monitor 400, or other specialized equipment. As illustrated in FIG. 6, ARIP system 130 is configured to superimpose an AR-based instrument positioning map 505 on a real-world imagery (e.g., the patient's 501 body) processed by the image tracking device 170 and display the combination of these on the display device 180 and/or the user computing entity 110A. The exact alignment of the patient's 501 body and the AR-based instrument positioning map 505 is important. As such, the ARIP system 130 is configured to accurately align both the patient's 501 body and the AR-based instrument positioning map 505 using an ARIT 503 placed on the patient's jugular notch 1101 of FIG. 11. This patient-oriented AR-view facilitates the optimal placement of electrodes of the 12-lead Holter monitor 400. The patient 501 feels confident to position the electrodes of the Holter monitor 400 themselves with the use of the AR-based instrument positioning maps as a guide.

C. ECG Testing Prep Usage Methodology and Exemplary Data Flow

FIGS. 7A and 7B illustrate various interactions between the following system components show in FIG. 1: clinician user computing entity 701, ARIP server 140, and image tracking device 170. Referring now to FIG. 7A, the process illustrates example operations performed by ARIP server 140 for generating the instrument positioning map for a particular patient and associating the instrument positioning map to a visual landmark (e.g., ARIT).

The process illustrated in FIG. 7A starts at step 702 where the clinician user computing entity 701 logs in to the ARIP application (app). In this case, the ARIP server 140 provides the ARIP app and upon activation of the ARIP app by the clinician user computing entity 701, provides a login interface that facilitates entering a valid username and password. The ARIP server 140 authenticates the entered username and password, and then redirects the ARIP app to an appropriate graphical user interface if the authentication is successful. In step 703, the ARIP server 140 identifies and transmits a list of patients for display on the ARIP app. When logged in as a clinician account, the clinician accesses an ECG testing preparation interactive support interface comprising the list of patients. Alternatively, if the patient logs in, the patient accesses the patient-at-home ECG testing interactive support interface which is discussed in further detail below. In other embodiments, the clinician-specific and patient-specific functionality may be separated into different apps (a clinician-specific app and a patient-specific app). In such embodiments, a patient attempting to log into the clinician specific app may receive an error message with instructions redirecting the patient to install the patient-specific app. Similarly, a clinician attempting to log into the patient-specific app may receive an error message with instructions redirecting the clinician to install the clinician-specific app.

In step 704, the clinician user computing entity 701 displaying the ECG testing preparation support interface further provides the clinician the ability select a patient and an AR image target. As shown in FIG. 10 a number of precordial (e.g., chest) electrodes and placements are required. The clinician must be careful to select to an AR image target that does not cover any of the electrode mapping locations shown in FIG. 10. In some embodiments, the ARIP server provides a recommended image target based on the Holter/ECG monitor associated with the patient. To facilitate selection of a patient, the ARIP server displays a listing of patients as shown in an exemplary list of patients illustrated by tables 900 and 903 of FIG. 9. Table 900 illustrates a list of registered patients where each patient row 902 includes patient information 901 including the patient identification, last name, first name, middle name, date of birth, gender, and last visit date (e.g., last visit with the clinician). Once the clinician using the clinician user computing entity 701 selects a particular patient such as, for example patient John Smith, the ECG testing preparation support interface renders for display table 903 illustrating a list of requested ECG tests. Each row 905 of table 903 includes ECG test information 904 including the ECG order identification, the visitation identification, the requested date and time for the ECG test, the status of the ECG test, the ECG test, and the ECG device.

Returning to FIG. 7A, upon the clinician selecting a particular patient and associated ECG test, the ARIP server 140 is configured to acquire data from the instrument positioning repository as shown in step 705. The data retrieved from the instrument positioning repository is data related to the selected patient. In step 706, the ARIP server 140 is configured to identify and transmit an instrument positioning map for display on the ARIP app based on the selected patient and AR image target. Thereafter, as shown in step 707, the clinician user computing entity 701 displaying the ECG testing preparation support interface further provides the clinician the ability select and input instrument positioning locations (e.g., electrode position markers). The clinician's selection and input of the instrument positioning locations is based at least in part on the identification of the physiological characteristics and anatomical landmarks of each patient. In an example embodiment, the ARIP server 140 may be configured to cause to display on the ARIP app electrode placement guidelines provided by ECG monitoring device manufacturers. In this case, the clinician may thoughtfully input the instrument positioning locations using the ARIP app electrode placement guidelines provided by ECG monitoring device manufacturers. Consistent with health organizational policies, HIPAA, or any other privacy or security laws, such ARIP app electrode placement guidelines or any training content, media, or video provided by the ARIP app will utilize generic references and images, such as three-dimensional (3D) computer generated imagery (CGI) models of a human body. Additionally and in some embodiments, the clinician user computing entity 701 displaying the ECG testing preparation support interface further provides the clinician the ability to reposition each instrument positioning location. In an example embodiment, the ARIP server 140 may be configured to update one or more instrument positioning locations based on the clinician repositioning an instrument positioning location.

In step 708, the instrument positioning map 707 is rendered to the clinician user computing entity 701. FIG. 19 illustrates an exemplary instrument positioning map projected on a display device 1900 using AR image target 1901 (e.g., ARIT). In step 709, the image tracking device 170 is configured to track real-time data comprising the patient's torso as illustrated in FIGS. 5 and 6. In step 710, the clinician using the clinician user computing entity 170 may customize the instrument positioning map using the real-time image data. Upon completion of the customization of the instrument positioning map as depicted, the clinician user computing entity 170 transmits the customized instrument positioning map to the ARIP server 140 using the ARIP app as depicted in step 711. In response, the ARIP server 140 generates a barcode (e.g., a two-dimensional barcode or other unique identifier) and associates the barcode with the instrument positioning map as depicted in step 712. In step 713, the ARIP server 140 is further configured to save the instrument positioning map to the instrument positioning repository for later retrieval.

FIG. 7B illustrates the clinician-guided mapping process utilizing a real-time image tracking of patient's body (specifically, a patient's torso) within an AR-view environment to facilitate placement of electrodes and ECG leads. In step 720 the ARIP server 140 is configured to render a default or preliminary AR-based instrument positioning map based on a patient identifier. The patient identifier may be any patient identifying data such as the patient's chest size or testing needs in order to select the appropriate ECG monitor. To properly render the instrument positioning map onto the patient's body, an ARIT is utilized and placed on the surface of the patient's body at a known location and thus provides the ARIP server 140 with points of reference. In the specific embodiment of the figures, the clinician places a neck lanyard including the ARIT on the patient so a marker (e.g., the black shape at the top of the ARIT) as shown by drawing 1102 of FIG. 11 overlays the patient's jugular notch 1101. In some embodiments, the neck lanyard includes a barrel cord lock (or other adjustment feature) which can be adjusted to hold the image target in position. As can be seen in drawing 1100, AR image targets (ARIT) may be provided and/or generated in different sizes, shapes, and with different barcodes for each patient. Such variations in sizes and shapes may be provided to accommodate differences in patient sizes, posture, or electrode placements.

After placement of the ARIT on the torso as shown in FIG. 12A, the clinician may initiate the mapping process using an “app” such as the ARIP application. Similar to FIG. 5, FIG. 12A includes a display device 1203 and/or user computing entity 110A, image tracking device 1202, the ARIT 1205, or other specialized equipment such as a wireless air mouse 1200 or other non-contact control responsive to gestures or movements of the user. As illustrated in FIG. 12A, the ARIP application displays on the display device 1203 a digital image comprising the patient's torso or in this example, a mannikin 1201. The ARIP application is further configured to superimpose a mapping location marker 1204 (e.g., visual marker cue), using the wireless air mouse 1200, on the displayed real-world imagery of the mannikin 1201 processed by the image tracking device 1202.

In some embodiments, movement of wireless air mouse 1200 may be translated by the ARIP application into movement of the mapping location marker 1204 on the display screen of the display device 1203. Referring now to 12B, to begin the present invention's execution of the AR-based instrument positioning map guidance, the clinician places his finger 1206 over a first electrode position on the mannikin 1201 and then uses the wireless air mouse 1200 or some other mechanism for electronically recognizing the location of the clinician's finger to mark the location in the AR environment, thereby setting the desired location of the first electrode. Thus, in the present example, the mapping location marker 1204 assists the clinician in identifying the location at which the clinician must correctly position the first electrode, as shown in the included visualization on the display device 1203 in FIG. 12B.

In some embodiments, using the clinician's finger and the wireless air mouse 1200 (or other mechanism for electronically recognizing the location of the clinician's finger), the clinician is able to select specific instrument positioning locations of the patient's torso. In other words, the clinician identifies the patient's anatomical landmarks and inputs or applies, using wireless air mouse 1200, instrument positioning location markers, such as circle shapes, square shapes, etc. Other types of markers can be inserted as AR content, such as comments, audio, or links. Once the instrument positioning location markers are inputted by the clinician and tracked or detected by the ARIP application, they are recorded and displayed. The ARIP application is then configured to associate the one or more instrument positioning location parameters (e.g. x, y, and z locations in 3D space) and recordings to the ARIT 1205 and is stored locally on the clinician client device and/or the physician client device. In this case the instrument positioning locations and the ARIT 1205 are linked.

FIGS. 12A and 12B illustrates an example proper placement of the ARIT at a known location so as to enable the ARIT to be used as a known visual landmark on the patient's torso in order to facilitate identification of a first mapping location of a first instrument relative to a known visual landmark (e.g., ARIT) as depicted in step 724. As shown in FIGS. 12A and 12B, a clinician may begin by placement of a first electrode within the AR environment, however it should be understood that in certain embodiments, additional setup may be required. For example, with reference briefly to FIG. 13, the clinician may first locate the left and right clavicular lines (extending parallel with the length of the patient's torso (e.g., vertically, while the patient is standing) in a manner similar to that discussed in reference to FIGS. 12A and 12B. The left and right clavicular lines (or other reference lines/points placed onto the patient's torso within the AR environment) may be used as reference points for later placement of electrodes, such as in accordance with the processes and methods as discussed herein.

In step 726, the ARIP server 140 is configured to automatically map a location of a second instrument on the instrument positioning map based on the first mapping location of the first instrument. Once the clinician or patient places the ARIT on the patient, invokes the ARIP app on their user computing entity, and scans the ARIT to render the AR-view, guidance is provided via an AR overlay reflective of the generated instrument positioning map over the digital image of the patient's body. For example, FIG. 13 illustrates the AR overlay positioned using the ARIT 1301 providing guidance to the clinician to locate the Right Arm (RA) 1305 electrode location below the patient's right clavicle, and between the right midclavicular line 1302 and shoulder. Once the first mapping location (e.g., RA 1305) is identified by the clinician marking the location of the first instrument using a wireless air mouse, a second instrument location (e.g., electrode location) may automatically be identified, for example, if the second instrument location is dependent on the positioning of the first mapping location. For example, the Left Arm (LA) 1304 electrode mapping location is automatically added and displayed in a mirror position to the RA 1305 mapping location.

Returning to FIG. 7B and step 728, the ARIP server 140 is configured to continue mapping locations for other instruments (e.g., electrodes) until all the instruments are mapped. Guidance for selecting the remaining electrode positions V1-V6, Left Leg (LL), and Right Leg (RL) is illustrated in FIGS. 13-17 using the AR overlay reflective of the generated instrument positioning map over the digital image of the patient's body. The remaining electrode positions may be set by a clinician in a manner as discussed above in reference to the first and second electrode positions, for example, with the clinician selecting a specific location on the patient's torso and electronically marking the location, thereby placing an electronic marker on the imagery of patient's torso within the AR environment corresponding to a particular electrode. The electrodes may be placed in series, such that a clinician sequentially marks the location of each of the plurality of electrodes, and the ARIP server 140 sequentially stores the locations of these electrodes as discussed herein. In step 730, the ARIP server 140 is configured to save the instrument positioning map and thereafter as depicted in step 732, the ARIP server 140 is configured to generate a barcode (or other unique identifier) to identify the instrument positioning map. This barcode contains (or links to a data storage repository containing) the instrument positioning map comprising the electrode position data for this patient, thereby capturing the clinical guidance that will benefit the patient at home.

D. Patient-At-Home Testing Application Usage Methodology and Exemplary Data Flow

FIG. 8 illustrates various interactions between the following system components show in FIG. 1: patient user computing entity 801, ARIP server 140, and image tracking device 170. Process 800 illustrates example operations performed by ARIP server 140 for provisioning the instrument positioning map for a particular patient at home. At this point in ECG testing, the patient has undergone the clinician-guided mapping processes and is equipped with the ARIT used to render the instrument positioning map and the Holter monitor. An example ARIT 1800 used by the patient is illustrated in FIG. 8.

Process 800 begins with step 802 where the patient user computing entity scans the barcode found on the ARIT with the ARIP app or otherwise provides data indicative of a unique identifier associated with the patient-specific electrode mapping. In step 803, the ARIP server is configured to retrieve the instrument positioning map associated with the barcode (or other unique identifier) from the instrument positioning repository and any supplementary data (e.g., instructional video providing information regarding how to wear the neck lanyard and ARIT, an electronic pdf guide of the mapping locations of the various electrodes, other educational information, etc.). In step 804, the ARIP server identifies and transmits the instrument positioning map for display on the ARIP app based on the barcode. In step 805, the instrument positioning map is rendered on the patient user computing entity 801. In step 806, the image tracking device 170 is configured to track real-time image data and in step 807, the patient user computing entity 801 is configured to facilitate identification of a mapping location of each instrument using the instrument positioning map and the real-time image data.

In an example embodiment, the ARIT may be placed in a field of view of the image tracking device 170 at a predetermined position on the patient's body as determined during the clinician-guided mapping process. The ARIT serves as a reference point. The instrument positioning map may be overlaid in relation to a position, orientation, and size of the ARIT in the real-world environment. In this case, the ARIP server will overlay the instrument positioning map on the real-time image data and will further align the instrument positioning map to the orientation and scale of the real-time image scene (e.g., patient's body) even if the patient moves around.

The ARIT is analyzed by the ARIP server to determine the instrument positioning map. As discussed above, each ARIT includes an instrument positioning map unique to a particular patient. The ARIP server may then provide on the display of the patient user computing entity 801, an AR-view comprising a real-time view seen through the image tracking device 170 overlaid with the instrument positioning map. The instrument positioning map is displayed according to the size, position, and orientation of the ARIT.

Upon rendering for display the AR overlay reflective of the generated instrument positioning map over the digital image of the patient's body, utilizing the ARIT of the instrument positioning map, the relative location of the one or more instruments (e.g., electrodes and ECG leads) may be determined. In an example embodiment, one or more mapping locations of each instrument is displayed on the instrument positioning map for positioning and orienting on the patient's body of the real environment for AR visualization. In some embodiments, the mapping locations may all be displayed simultaneously, or the mapping locations may be displayed sequentially, so as to guide the patient in a step-by-step fashion regarding how to place the instruments. For example, the ARIP app may provide an option to view a step-by-step guide and the ARIP app is configured to display a breakdown of the individual step-by-step instrument mapping locations. In some embodiments the step-by-step guide option may allow the user to move sequentially through the step-by-step guide. Additionally or alternatively, the ARIP app may provide an option to view a completed guide in which the ARIP app is configured to simultaneously display all the instrument mapping locations on the instrument positioning map. In other words, the entire collection of instrument mapping locations are simultaneously displayed and may be arranged so that all of the instrument mapping locations appear separately from each other.

FIG. 19 illustrates one example display that may be provided to a patient to facilitate placement of a plurality of electrodes on a patient body. As illustrated in FIG. 19, the patient is prompted by the ARIP app with an instructional video to align the top of image target 1901 with his/her jugular notch, or other anatomical landmark if applicable, such that the image target may be used as a visual landmark used for reference against the placement of the electrodes. The ARIP is then configured to display a patient-oriented AR view 1900 to self-place the electrodes and ECG leads using the same guidance as provided by the clinician and reflected within the instrument positioning map. As can be seen in FIG. 20, the instrument positioning map moves and may be repositioned according to the patient's detected body movement.

E. AR-Based Instrument Positioning Map

In an example embodiment, the ARIP app is further configured to manipulate the AR-view as depicted in FIGS. 21-24. FIG. 21 illustrates operations related to AR-view enhance actions for manipulating the instrument positioning map. In an example embodiment the user may move, turn, walk around as long as the ARIT can be tracked and processed by the ARIP app. In an embodiment, when a change in movement is detected by the ARIP app, the instrument positioning map is provided in a geometrically correct orientation with respect to change of movement by the user. The instrument positioning map may be determined to be properly positioned when the ARIT is just below the user's right clavicle. If the ARIT is not properly positioned, a warning that the ARIT is not properly positioned may be displayed to the user via the ARIP app. In another example embodiment, if the ARIT is obstructed in any way, the ARIP app may not render the instrument positioning map and may further provide a warning to the user.

Once the ARIT is properly positioned, the instrument positioning map is generated and shown to the user using graphical mapping locations in an AR view. The ARIT may be determined to be properly positioned when image target requirements for the instrument positioning map are satisfied. For example, the image target requirements may correspond to image quality factors (e.g., distance ARIT is from the image tracking device, etc.) that should be satisfied before the instrument positioning map is generated.

In some embodiments, the user may be allowed to change the appearance of the instrument positioning map. As shown in FIG. 21, the ARIP app provides a resizing graphical user interface 2100 comprising a variety of actions to re-size the AR overlay reflective of the generated instrument positioning map over the digital image of the patient's body. For example, upon selecting action 2101, the instrument positioning map increases its width up to a predetermined limit. In FIG. 22, the ARIP app provides an action 2200 to scale up 2201 the instrument positioning map to a predetermined limit. In some embodiments, the ARIP app is further configured to scale up the mapping locations. In FIG. 23, the ARIP app provides an action 2300 to scale down 2301 the instrument positioning map to a predetermined limit. FIG. 24 illustrates the user selecting action 2400 to decrease the width 2401 of the instrument positioning map. As can be seen in FIGS. 21-24, the AR overlay may be further resized and manipulated to better suit the user's body size.
